EDIT: I was getting the exact verbage for the error, and my computer locked up before I finished the post. All, I constructed a relatively simple database to store contact info for media buying (advertising). One table contains all the info (name, address, email, phone, remit address, negotation, couple of memo fields, etc). There are a few queries, and a couple of reports based on those queries. I made a simple front end, consisting of a form to enter/edit the data table, and a simple switchboard to navigate. PROBLEM: When the form is brought up, you can enter data. But, if I touch the scroll wheel, the form rapidly scrolls through all records (just one tick on the wheel, mind you). If I touch the wheel a couple of times (up and down), eventually an error comes up.
